Morning guys. I have question about Pulumi in azure-native. In this config:

import * as pulumi from "@pulumi/pulumi";
import * as azure_native from "@pulumi/azure-native";

const database = new azure_native.sql.Database("database", {
    databaseName: "testdb",
    location: "southeastasia",
    requestedBackupStorageRedundancy: "Zone",
    resourceGroupName: "Default-SQL-SouthEastAsia",
    serverName: "testsvr",
});

Which values of

requestedBackupStorageRedundancy

can be use in this config? I can't find any document mention about which value can be use here. Thanks.
